The top five happiest countries in the world are all Scandinavian, according to a United Nations report released Wednesday.

Denmark reclaimed the top honors in the World Happiness Report, booting Switzerland from the No. 1 spot.

Rounding out the top five were Iceland, Norway, Finland and Sweden.

“In Norway, it’s quite common for people to paint each other’s houses even though they can all afford to pay to have their houses painted,” John Helliwell, who is director of the Canadian Institute for Advanced Research and helped edit the fourth annual report, told CNN.

“They go out of their way to help each other and it becomes a social event and those events are enormously supportive of well-being,” he said.

The United States didn’t make it into the top 10, but did jump two spots up from last year to No. 13, trailing behind its neighbor Canada, which dropped one spot to No. 6.

“The message for the United States is clear,” Sachs told Reuters. “For a society that chases money, we are chasing the wrong things. Our social fabric is deteriorating, social trust is deteriorating, faith in government is deteriorating.”

There is no scientific measurement for happiness, so the report relies on a variety of indicators including per-capita gross domestic product, life expectancy, freedom to make life choices and generosity to rank 157 countries.

Jeffrey Sachs, who heads the Earth Institute at Columbia University and helped edit the fourth annual report, said all countries should include happiness on their agenda.

“Indeed the goals themselves embody the very idea that human well-being should be nurtured through a holistic approach that combines economic, social and environmental objectives,” he said in a statement.

Burundi, a landlocked country in East Africa that has been plagued by civil unrest following a contentious 2015 election, bottomed out the list.

Syria, a conflict hotbed ravaged by a years-long civil war and ISIS terrorists, was the second-least happy country followed by Togo, Afghanistan and Benin.
